We liked our stay at sanctuary house. It is a basic accommodation but had everything we needed(AC, strong wifi, small kitchen, clean bathroom). We appreciated the very clear instructions from the host about the property/check-in and transportation(although we probably walked/used MRT more than he recommended, but we like slower travel modes to see the real city in between destinations.) It's a good location, central enough to be easy to get around but also away from the main streets enough to not be too noisy. 7/11 close by was convenient, we also recommend landin coffee and mai thai massage near the apartment.
The only 2 things that weren't great for us would be a bit of a hard bed(which I am coming to see as just a common thing in asia as I travel here more) and we did get a cockroach visitor in the bathroom on our last day which I'm guessing that isn't too odd for average thai style accomodations.
